Evaluation of Manufacturing Capability for the Job Shop by Combining the Entropy Weight Method with Grey Relational Analysis

As a key factor for making decisions for production scheduling, manufacturing capability has been attracted great attention by academia and industries. With the increasing customized and personalized needs, modern manufacturing enterprises need to fabricate products at low cost, at right time, and at high effectiveness. Therefore, it is necessary to optimize the manufacturing system in order to improve productivity and the competitiveness of enterprises. The analysis and evaluation of manufacturing capabilities play an extremely important role in the optimal scheduling of production. In this paper, the manufacturing capability of a job shop is investigated. The indicator system is built for evaluating the manufacturing capability of a job shop and an evaluation method is proposed based on the combination of the entropy weight method and the grey relational analysis. Finally, a case study is used to validate the method.
